2F-Viminol
2F-Viminol is a fluorinated analogue of viminol, a pyrrole-derived analgesic. It is grouped with dissociative and research-chemical products but is pharmacologically an atypical opioid-like analgesic, with one diastereomer acting on opioid receptors. Human data are essentially absent and its risk profile is poorly defined.
01 Overview
Viminol is an older analgesic whose activity depends heavily on its stereochemistry, with certain isomers behaving as opioid agonists. 2F-Viminol is a fluorinated derivative sold as a research chemical; almost nothing is published on its human pharmacology.
Because part of its activity is opioid-like, respiratory depression and dependence are plausible concerns, and combining it with other CNS depressants would compound that risk. Purity and isomeric composition of grey-market material are unknown, making effects unpredictable.
02 Mechanism
Pyrrole-derived analgesic; certain stereoisomers act as opioid receptor agonists, so activity is stereochemistry-dependent.

04 Effects
| Effect | Magnitude | Evidence | |
|---|---|---|---|
| AnalgesiaPain relief inferred from viminol's opioid-like activity. | Unconfirmed | ||
| SedationCNS depression and drowsiness. | Unconfirmed |
05 Side effects
| Effect | Severity | Frequency | Evidence | Countermeasures |
|---|---|---|---|---|
| Respiratory depressionOpioid-like activity implies risk of respiratory depression, worsened by other depressants. | Life-threatening | Unknown in humans | Unconfirmed | |
